/* PR target/11087

   This testcase was miscompiled on ppc64, because basic_induction_var called
3
   convert_modes, yet did not expect it to emit any new instructions.
4
   Those were emitted at the end of the function and destroyed during life
5
   analysis, while the program used uninitialized pseudos created by
6
   convert_modes.  */
